The dispute within the Taliban threatens a fledgling peace process with the Afghan government and may open the way for Islamic State to expand its toehold of influence.
The Taliban in July officially confirmed Mullah Omar had been dead for more than two years, after the Afghan spy agency leaked the news. The next day, a hastily convened meeting appointed Omar’s deputy, Mullah Mansour, as leader.
Many commanders and Omar’s family were unhappy with the appointment. Some question why Mansour concealed news of Omar’s death for two years. He said it was necessary to preserve unity amid the 2014 NATO withdrawal. Rumours have multiplied amid the splits.
“I wanted to assure you that he died a natural death,” Omar’s eldest son, Mullah Mohammad Yaqoob, said in an audio tape released on Sunday night and authenticated by Taliban sources.
“He had been sick for some time but his condition deteriorated,” he said. “We made enquiries from the doctors, it seems he was suffering from HCV (Hepatitis C).
“He stayed in Afghanistan even after the US-led invasion of Afghanistan. He died there and was laid to rest there.”
The tape, Yaqoob’s first public audio statement, rejected the idea that his father had appointed a successor, in an apparent jab at Mansour.
“He had not appointed any one as his successor,” he said.
Mansour, a strong tactician backed by some of the most powerful field commanders, enjoys good relations with neighbouring Pakistan, which is often accused of backing the insurgency.
The Afghan insurgents fear Pakistan wants to manipulate their movement for its own ends, worries Yaqoob referred to.
“Our enemy is the U.S.-backed Afghan government,” he said. “There are some Islamic countries which are also standing alongside our enemies.”
Some militias affiliated to the Taliban have already pledged allegiance to Islamic State, the group dominating Iraq and Syria.
Yaqoob, 27, stopped short of claiming the leadership.
“If unity can return with my death, I am willing to carry out suicide,” he said. “We are ready for whatever order the council gives us. We are ready to work in any capacity, whether on a high level or a lower level.”
